IMPROVEMENT IN GUTLERY.

@Le Srlgnm'lc netta; tu 'iu tlgcse Etnias ttent mit mating putt tf tigesamt TO ALL WIIOM IT MAY CONCERN:

Be it known that I, JONATHAN BALDWIN, of Northampton, Hampshire county,Commonwealth ot' Massachusetts, have invented a new and useful ImprovedMethod of Attaching Knit`e-IIandles to the Blade without the use ofRivets; and I do hereby declare that the/following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

My improved method of fastening consists in attaching the two scales eneach side of the tang of an ordinary house-knife by means oi' metalpoured in through a slot or slots in the tang or scales themselves,which shall run through the tang at certain openings and iill intodove-tailed slots in the scales, and on hardening shall bind the wholetogether firmly. The shoulders at the junction o'l the blade and haftcan also be attached in a like manner. In the drawingv Figure 1represents side view of the tang of the knife, one scale having beentaken o" and the metal fastening cut ott` where the junction was madebetween the deve-tails on either side, and shown in the figure by thesection lines. In this A A is the groove or slot cut lengthways throughthe tang B and filled with the east metal. At C C are the connectingpoints where the metal runs either side into the dovetailed slots eutinto the scales. At these points the groove in the tang ismerelyenlarged so as to allow ,the metal to till the dove-tails morereadily. D and D are small connections between the dove-tails 'at C',which serve to bind this point more strongly. AtE is a square slotthrough the tang, and forming the end of the slot A. This serves to makea connection between the shoulders F F, the shape of which is shown inFigure 3, where is shown the east metal filling the dove-tailed chambersa a, and attaching them together against the sides of the tang.

Figure 2 shows a plan View of the handle of my knife, in which is seenthe manner in which the poured metal binds the scales X and Y to thetang. In iig. 1 it is seen thatV the slot A in the tang does not extendentirely to the end, but leaves asmall connection between the upper andlower portions, in order that the metal can be poured into this slot. Atthis end a small groove, o, in each scale through which the metal runsin the slot A, is eut. This also forms a shoulder to prevent the scalesfrom slipping back. The position of these grooves is shown by dottedlines in either figure. rEhe metal used for filling may be a'eompositionof white metal and of' any suitable hardness. i

By this means I accomplish the fastening of the scales and shouldersupon 4the tang without the use of rivets, makinga very neat handle andavery strong one, for the metal in cooling, after it has filled up thedove-tailed grooves, shrinks and binds the whole together much moreiirmly than could possibly be done with rivets or bands.

In my handle the shoulders can be fastened by rivets or any ordinaryway, while the sea-lcs can be fastened on in the manner alreadydescribed.-

New, having described my invention, what I claim as new, and desire tosecure by Letters Iatent, is-

l. The method of attaching the sea-les of a knife-handle to the tang, bymeans of dove-tailedv grooves eut. into the former into which metal isrun through the tang, substantially as herein described.

Q. ,lhe method herein described of attaching the'shoulders F F to thetang, by means of the dove-tailed grooves (l t and metal enst in,substantially :is shown.
